Application filed April 12, 1912.

Serial No. 690,402.

To all whom it may concern:

Be it known that I, VVELLS T. BARKER; a citizen of the United States of America, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvement-s in Dough-Rolling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in dough rolling machines and its object is to provide a machine that will form separate masses of dough or other plastic material into balls of uniform size, and to provide the same with various new and useful features hereinafter more fully described and particularly pointed out in the claims.

My invention consists essentially of a horizontally disposed rotating disk above which are arranged spiral vertical walls and vertically adjustable cap plates above the walls and partially between the same, opposite the disk and spaced apart therefrom forming a passage through which the material is rolled, as will more fully appear by reference to the accompanying drawings, in which:

Figure 1 is a vertical section representing a device embodying my invention; Fig. 2 a detail of the driving gear as shown at right angles to Fig. 1; Fig. 8 an inverted plan showing the spiral walls and under side of the top plate; Fig. i is a detail in vertical section through the disk, top plates and hopper; and Fig. 5 is a detail in vertical section through the joint of the top plate and extension,

Like numbers refer to like parts in all of the figures.

1 represents the driving shaft of the machine.

2 represents a vertically disposed post or standard on which is rotated a sleeve 3 connected to the driving shaft by means of gears 4 and 5 the form of gears shown being spiral gears. Supported upon the upper end of this sleeve is a horizontally disposed disk 7 carried and rotated by the sleeve.

8 is a non-rotating sleeve on the post 2 vertically adjustable thereon by means of rods 9 secured to the sleeve at the lower end and connected at the top by a yoke 10 in which yoke is an adjusting screw 11 engagmg the end of the post whereby the sleeve 8 is adjustably supported by the screw. Fixed on the lower end of this sleeve is a top plate 12 arranged opposite the disk 7 and spaced apart therefrom more or less according to the adjustment of the screw 11.

Surrounding this top plate is a spirally disposed wall 14 preferably of sheet metal the inner end of which is vertically reduced and prolonged beneath the top plate as at 14: and extended to a point near the axis of the machine. This spiral wall is arranged close above the disk at the lower edge and the margin of the top plate is close to the inner side of this spiral wall throughout the circumference of said plate. This wall 111 is of such length as to form substantially two complete circuits and the space between the circuits is progressively reduced as it extends outward from the axis. The periphery of the top plate is within the inner circuit and is turned downward in a curve close to the inner side of the wall 14.

An extension of this top plate 12 is secured to thesame where it terminates in a radial line, and both edges of this extension are turned downward between the convolutions of the spiral wall and its length is substantially one half of a circuit.

Extending through the top plate is a hopper 19 having a bottom opening through the plate to receive and discharge the material upon the rotating disk. This hopper is located close to the inner surface of the inner convolution 14 of the wall 14: prefer ably near where it is reduced in vertical width to extend under the top plate. A spirally curved vertical wall is also provided between the top plate and the disk which wall commences near the side of the receiving opening near-est the axis of the machine and extends thence spirally around the axis gradually approaching the wall l t and spaced apart therefrom. The wall 1 1 is carried on hangers 15 supported by a spider 13 fixed on the post 2 being extended upward to the top of the post and through the upper part of the spider, the rods 9 slidably extend, to adjust the top plate vertically. The wall 16 is also carried by the spider on hangers 17 and 17 the hangers 17 being intermediate the ends of the wall 16 and radially adjustable in a slot 18 in one of the arms of the spider whereby the co11- vergence of the walls 14 and 16 may be adjusted and the end of the wall 16 permitted to spring away from the wall 14.

In operation the disk 7 is rotated by any suitable power applied to the pulley on the shaft 1. The dough or other plastic material divided into proper portions is dropped into the hopper 19 and falls upon the rotating disk and from thence is carried by the disk between the converging walls 14c and 16, the stationary top plate 12, and the rotating disk. I This produces a rolling action on'the material,compresses and rounds the same, which escaping from between the walls 14 and 16 is carried along the inner surface of the wall 14 by the disk and thence between the inner and outer convolutions of this wall and under the concave extension 12, being finally discharged from the narrowed end of this passage and off from the edge of the disk as indicated by the arrows being rolled and compressed into spherical shape by the machine.

What I claim is z- 1. A dough rolling machine, comprising a rotative disk, means for rotating the same, a spiral wall above the'disk relatively fixed with respect to the rotative disk, means for rigidly supporting said wall, a top plate above the disk and spaced apart therefrom, and means for adjustably supporting said plate.

2. A dough rolling machine, comprising a rotative disk, means for rotating the same, a spiral wall above the disk and relatively fixed with respect to the disk and arranged to form a progressively reduced passage between its convolutions, means for rigidly supporting said wall, a top plate supported abovethe disk and having an opening to receive the material within the inner convolution of the Wall, and means for rigidly supporting said top plate.

3. A dough roller, comprising a rotative disk, a spirally arranged wall above the disk and relatively fixed with respect to the latter and having one end near the axis of the disk and its other end near the periphery of the same and arranged to form a progressively reduced spiral passage between its convolutions, means for rigidly supporting saidwall, a vertically adjustable top plate having its margin extending within the inner convolution of the wall, an extension of said plate extending between the overlapping convolutions of the wall and vertically adjustable means for supporting the plate and extension;

at. A dough rolling machine, comprising a horizontally disposed disk, means for rotating said disk, a fixed spiral wall above the disk beginning near the axis of the disk and extending to near the periphery thereof and also forming a progressively reduced passage between its convolutions, the inner end of the wall being vertically reduced to extend under a top plate, a top plate above said inner end and having a downwardly turned margin close to one convolution of said wall, an extension of said top plate having both margins turned downward between the convolutions of said wall, vertically adjustable means for supporting the top plate, and fixed means for supporting said wall.

5. A dough rolling machine, comprising a. rotative disk, a spirally arranged wall beginning near the axis of the disk at one end and having its convolutions spaced apart to form a spiral passage, said wall being relatively fixed with respect to the disk, means for rig idly supporting said wall, a hopper to deposit material within the inner convolution of said wall and a second curved wall beginning near the hopper and spaced apart from the first named wall to form a passage therebetween beginning at the hopper, a top plate,

I and means for supporting the top plate.
